Stock smashs craft, have history of hundred thousands of years at least. Archaeology discovery, be apart from the ” of “ Yuanmou Man that has 1.7 million years about today, there already was stone tool in its culture hangover, it is breaking equipment of the first stone. In be apart from the stone vessel that the place of ” of “ Peking Man that has 40~50 all ages about today uses, one part is control block into the rock that takes blade piece, in the course bosseyed treatment is made. Chipped stone implement is used be engaged in chopping be bungled and scrape, these are ancient mankinds smash in what what be engaged in in the life and labor exercise, can regard as contemporary the earliest origin that smash.
In ancient time, beetle of people hair palpability, joint of bones, grind, grind wait for a lot of smashing tool, they still have in modern life use. Until 1858 ground E.W.Blake to invent compound pendulum type crusher and crusher of the first cycle came out 1878, stock smashs the important process that just becomes industrial branch.
In fact, people is being produced and stock cannot leave to smash everywhere in the life. All sorts of stock that people smashs one year, according to estimating its gross is 10T. Stock smashs craft applies extensively at, mine, chemical industry, electric power, pottery and porcelain, cement, building, build the industrial department such as road and fireproof material.
Stock smashs is a high cost can, Gao Gang bad news, inefficient process. According to statistic, in a lot of world nations, smash the 4%~5% that the electric energy that waste takes total electric energy about, be in an ore dressing plant, crusher specific power consumption takes waste time of whole mineral separation about can 40%~70% , scale and position are very significant.
Smash the task of exercise is contented country name economy is to all sorts of stock products on the amount and granuality, particle size distribution, solution leaves degree, corporeal composition, surface is physico-chemical the pressing demand of a lot of respects such as property. 20 centuries 70 time, be opposite to satisfy smash the increases increasingly demand on product measure, appeared to smash facility is large the upsurge that change.
Enter 21 already after the century, the rapid development that breaking equipment welcomes, introduced the advanced technique of the country such as the United States, Germany, Japan, Australia and technology early or late, built the product line with advanced international and top-ranking modernization to detect base, established laboratory of lab of arenaceous stone machine, crocus machine lab, mineral separation equipment. History of ceaseless understanding breaking equipment looks into future, production of proper motion development gives impact type crusher, new-style control the high production such as grinder of arenaceous machine, large high pressure the new and high product of low cost.
